Just because, say, XI's Monk had no resource management is not a proper justification to exclude it here.
In 11's case when Monk used kicks was not a buff, it was a different way of playing the class, another "stance" if you prefer.
You dont need to have a resource management to change from a Monk to Samurai (thats what kicks did in FF11).
In this case it's a buff that uses MP and its not even elemental.
Its not about immersion, I explained my reasons in the other thread, read it.
